This year, we purchased a 10 foot by 12 foot greenhouse just so we can grow more vegetables in the colder months here in Southeast Missouri.
Just because the days are getting shorter and the temperatures are dropping, it doesn’t mean that you have to set your gardening gloves aside. Winter isn’t just a time to dream wistfully of the bountiful harvests of summer – it’s also a great time to plan for the year ahead, as well as to jumpstart your garden for next year.
There are plenty of winter vegetables to grow, particularly if you live in an area that experiences mild winters. Even if you live in an area with more severe weather, there are plenty of ways to keep your garden growing throughout the coldest months of winter.
The 13 Best Winter Vegetables to Grow
Onions are easy to plant and you won’t have to do anything all winter. In most areas, onions have a long growing season and won’t be ready for harvest until next summer anyway. Just make sure you plan carefully because they will still be in the ground when it’s time to begin planting crops in the spring.
Garlic is an easy vegetable to grow and there are plenty of varieties to choose from. Even if you experience harsh winters, garlic can survive – you will just need to mulch it heavily to protect it from the heavy freeze. Consider growing options like Chesnok Red and Wight Cristo for a variety of culinary applications. You can learn how to grow garlic here and how to store garlic here.
Spinach is a cold-hardy crop that can grow throughout much of the winter months in many areas. For the best results, choose perpetual spinach varieties, which will yield you multiple cuttings throughout the season. Sow in the early autumn and you’ll have a crop well into early summer.
You may not be able to grow peas if you get a heavy snowfall, but in most cases, peas are quite cold hardy. Sow rounded variants in the fall for a headstart next spring. You can also learn how to preserve peas here.
Asparagus is a perennial and takes several years to establish. It can survive even the roughest winters in colder growing zones, and fall is the best time to plant it. Choose a variety meant to be planted in the fall, like Pacific Purple. Once you get it established, asparagus will produce up to 25 spears per year – for up to 25 years. You will need to be patient, but you will get a serious return on your investment.
One of the hardiest herbs you’ll find, parsley can sometimes survive up to zone 5 in the winter. It will yield bushy greens in the spring before going to spring. Curly parsley tends to be more frost-resistant than flat-leaf parsley.
Carrots can be grown outside well into the winter months in many areas. Plant them directly in beds and mulch heavily. Carrots that are hit with a frost are often sweeter, so it may actually be to your benefit to keep growing them throughout the colder months.
Leeks are inexpensive and produce a bountiful harvest. You can harvest them throughout the year and as long as you have a mild winter, you don’t have to worry about them dying.
Turnips grow great during the winter months. As long as temperatures remain just above freezing, you should be able to harvest both the roots and the tops during the winter months.
10. Leafy Greens
Kale, along with other cold-hardy leafy greens such as chard, lettuce, and bok choy, usually do just fine in the cold temperatures of the winter. You can usually harvest them straight through the winter months (and they’re great for chickens).
In fact, most greens perform better in the winter. In the summer, these plants often go right to seed. Just don’t forget to water and fertilize when growing greens during the winter – even though they won’t need as much water, the drying air of winter can still sometimes be a problem.
Depending on where you live, you might be able to grow potatoes all throughout the winter months. Although it’s not the best winter vegetables to grow, the potato is still a great option if you experience minimal snowfall. Learn more about growing potatoes in containers here and curing potatoes here.
Radishes mature quickly, with some varieties ready in just a month from when you have seeded them. They also don’t need a lot of heat – too much heat damages the texture and flavor of delicate radishes – so they’re perfect candidates for winter growing.
13. Broad Beans
A sturdier variety of green beans, broad beans can often be planted in fall gardens because they are heartier and more rugged than their narrower cousins. These plants can be grown directly in the winter garden in many areas with mild winters, or they can be grown in an unheated greenhouse.
Tips for Growing Vegetables in the Winter Months
Use a Hoop House or Greenhouse
Growing winter vegetables outdoors might be possible in areas that don’t experience hard freezes or heavy snowfall, but if you live in a colder climate, that might not be an option. However, if you have a greenhouse or hoop house (a greenhouse covered in plastic instead of glass, you can easily grow some plants throughout the entire season. Here are some plants to consider:
- Salad mixes (mustard, lettuce, land cress, etc)
You can even grow many flowers and fruits in your greenhouse, too!
If you have a greenhouse, you can choose to leave it heated or unheated. Some warm-weather plants, like tomatoes, peppers, and squash can even be grown during the winter months, too. As long as you heat the greenhouse and transfer these plants to pots, you may be able to get them well into the next growing season.
Consider a Cold Frame
Cold frames are a great way to extend your growing season, even if you live in a colder growing zone like 3 or 4. Essentially miniature greenhouse over your plants, cold frames can be purchased dor built inexpensively from scrap lumber and glass.
Just be sure to vent your cold frames, as too much heat can become an enemy to plants in the winter even more quickly than too much cold can. Trapping too much hot air inside can not only dry your plants out but it can also conversely lead to fungal issues should too much moisture also get in there.
Don’t have the time or resources to buy or build your own cold frame? Don’t worry. You can easily construct a DIY version by positioning hay bales on all sides of a planting bed and then covering the area between with old windows.
Don’t Forget About Dormant Plants
Some plants might not actually grow during the winter months, but they won’t die back, either. They will simply remain dormant until the temperatures rise and growth can resume. Consider planting a winter vegetable garden in the late summer or early fall so that the vegetables have time to get established before they go dormant.
Mulching can help protect your crops from becoming too dry or frozen. It will also keep the soil warmer when temperatures plummet. Consider using mulch materials like straw or dried leaves, which will help nourish the soil as they break down, too.
Do a Deep Clean
Even if you have a long list of winter vegetables to grow, that doesn’t mean you can neglect your normal fall planting chores. Cut away any dead foliage and make sure you throw out any diseased or damaged plants. This will prevent rot and also stop pest eggs from proliferating.
Know Which Plants to Bring Inside
Indoor gardening is a great option for many gardeners who can’t keep things going during the winter months, either due to extreme temperatures and precipitation or because they simply don’t want to garden outside during the winter.
Many plants can be grown inside in containers. Cold-sensitive plants like tomatoes and peppers are great candidates for this, as are many herbs.
Protect from Frost and Wind
You can’t control when a frost might strike, but you can take steps to protect your plants. Cover frost-sensitive varieties up with blankets, sheets, or row covers that are draped over stakes. This will help get them through brief cold snaps at the very least. You can also consider heating your greenhouse.
Select Ideal Varieties
Try a variety of crops to see what works best for you, keeping your growing zone and gardening preference in mind. You might also want to experiment a bit with timing to see what planting schedule and rhythms work. Put in new crops whenever you see an empty space and save seeds when you find varieties that perform exceptionally well in your area.
Why You Should Consider the Best Winter Vegetables to Grow
Winter gardening is a great way to keep the garden going all year long. Not only will it help satisfy your green thumb urges during the colder months of the year, but it will also provide you with plenty of healthy vegetables at a time when they are normally scarce on your dinner plate.
Plus, growing vegetables in the winter is surprisingly easy. They will naturally grow a bit slower, but you’ll have fewer weeds to contend with. You may not even need to water much between mid-November and mid-February!
You can start with this list of best vegetables to grow in winter. Try lots of crops to see what works best for you – perhaps start with just one this year and add more varieties as you gain experience. Stay warm!
